Bestler says the Minnesota author hadn’t completed the manuscript when he died June 19 at age 47, more than two years after being diagnosed with prostate cancer.

The book, titled “The Survivor,” was planned for release this fall.

Bestler says in a statement it’s too soon to know how much of the book was written or whether Flynn had made arrangements in case he could not complete the book. So she says publication is listed as “postponed indefinitely” instead of “canceled.”

Flynn wrote the Mitch Rapp counterterrorism thriller series. His 14th novel, “The Last Man,” was published last year.
